Super Aluminum Substrate 12W 1917 3 In 1 RGB Led Cob Chip 1919 Cob Led Chips
1917 3 In 1 RGB Led Cob Details
The RGB color model belongs to an additive color model. In this model, the primary colors of light, namely red, green, and blue, are combined in diverse manners to generate a wide variety of colors. Its name is derived from the first letters of these three additive primary colors.
The principal aim of the RGB color model is to facilitate the sensing, representation, and display of images within electronic systems like televisions and computers. Moreover, it has also found application in traditional photography. Even prior to the advent of the electronic age, the RGB color model had a robust theoretical foundation, which was rooted in human color perception.
